Brief description of our two models of three-dimensional, X-shape + spiral magnetic fields in galactic disks.

The free parameters and functions of models Bd and Dd are the same as those of models B and D, respectively (see Table 1 for the free parameters of the poloidal field and Table 2 for the free parameters and functions describing the azimuthal structure). The only difference concerns the power-law index of field lines asymptotic to the z-axis in model B (now restricted to n ≥ 2) or the r-axis in model D (now set to ).
Prescribed radius or height at which field lines are labeled by their height or radius, respectively, and by their azimuthal angle.
